Its a crazy rule. I am the only Cleric, So we wait a full 24 hours so that the party has healing. We then get another random encounter and the same happens again. so 48 hours later we are moving. It slows the game down and effects everyone. No need for it. its a 9 hour penalty. 8 for rest 1 for praying. Clerics dont get great skill points. Dont get loads of feats. rely on spells and this happens. Fingers crossed 5th Edit clears this up
I don't find it a "crazy rule". I'd note it doesn't apply to the Cleric alone - any spells used by any other spellcaster in the encounter will also be gone for the next day. Wizards and Sorcerors dont get great skill points. Dont get loads of feats. rely on spells - and the same rule applies to them.
Let's look at some alternate scenarios:
(a) The party decides to rest. During the rest period, they are attacked. After the attack, the cleric uses some spells. The party completes the rest period, and the cleric prepares his spells. He is missing the spells used during the rest period.
(b) The party decides to rest. The party completes the rest period without incident, and the cleric prepares his spells. Immediately after the rest period, they are attacked. After the attack, the cleric uses some spells. He is missing the spells used.
How does one scenario disadvantage the group more than the other? I would assert that it seems arbitrary that an attack five minutes after the Cleric's prayer time resulting in loss of spells for the day when an attack 10 minutes earlier would seem like a "crazy rule" to me.
There is no requirement that the party commence travels with their resources 100% available to them. So you're down a few spells? You move out down a few spells and life goes on. Would you insist on resting after the first encounter of the day because you're now down some spells, or do you move on? In my games, the party doesn't typically have the luxury of a 15 minute work day followed by a rest period so they can be at 100% for the next encounter.
Or you delay until you can move out with 100% of your resources available, and you'll have to deal with whatever additional preparations your 48 hour delay allowed your adversaries to undertake. Maybe:
- you don't arrive shortly before they complete the ritual to Summon a powerful Demon - it was summoned almost two days ago, and is ready and waiting for you.
- after your first foray, they have now had two extra days to heal, plan, fortify their base/home and lay traps for your party.
- maybe they used the same rest period to rest and regroup, then, when nothing showed up early the next day, sent war parties out tracking down those invaders. Since they now know where you are holed up, the war party launches the occasional diversionary attack (the encounters the first and second night) while the runner they sent back gathers all their forces to attack, well planned and en masse, early on the third day.
Better yet, perhaps you just picked a room in the enemies' lair to rest up in because "we're low on spells and hit points, so we have to rest". A friend of mine some years ago responded to complaints of the "unfairness" that they were attacked during such a rest period with "Seriously? This surprises you? This is basically the same as breaking into someone's house, then getting tired so you take a nap on his couch. What the ^@*# did you THINK was likely to happen?"
The clock doesn't stop running while the PC's finish their "time out".
